IMPROVEMENTIN NECK-VOKES.

Specification forming part of Letters Patent No. 172,004, dated January 11, 1 April 28, 1875.

To all whom it may concern.-

Be it known that I, ELLSWORTH ELY, of

Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Neck-Yoke Oenter-Gouplin gs, of which the following is a specification:

The nature of my invention consists of a cast-metal grooved or fluted neck-yoke ring,

provided with an eye at the top arranged at right angles to it, so as to receive the staple in such a position that when the two are connected they will hang in the same plane with each other and the staple so formed that said ring may have a free and more than ordinary lateral movement, as well as an easy backward and forward motion, the increased lateral movement being for the purpose of allowing the pole suflicient sway or side movement to prevent a sudden or violent wrench being given to the horses neck when a forward wheel is caught by a stone or other obstruction. The

. swaying of the pole in this manner often allows the wheel to pass around the obstruction, instead of passing over it, thereby making it much easier work for the horses.

In the accompanying drawings, Figure 1 is a front elevation of my invention, showing a part of a wooden neck-yoke and its connection thereto. Fig. 2 represents a section through line X of the ring. I

In said drawings, A represents the ring. It is provided with an opening, B, arranged at right angles to the inside or opening 0 of the ring. It is formed so as to present the shoul- 876 application field ders D D for limiting its lateral movement by. striking against the shoulders E E on the staple F. The dotted lines G show the shape of the staple where it passes through the ring. It is so formed and fitted for the purpose of allowing a sufficient lateral motion, and at the same time restrict the vertical movement of the ring, so as to prevent noise or rattling, and also to hold the ring as nearly in the center as possible.

The grooved or fluted form of the ring, while it adds to its appearance, insures the necessary lightness with suflicient strength.

H H represent two strengthening or bearin g plates, made fast close to the wooden neckyoke I, which, together with the ring and staple, are firmly held in place by the shoulders J J and the nuts K K, as shown in Fig. 1.

In the construction of this improvement I find malleable iron to be the best and cheapest material. v,

I claim as my inveution- A neck-yoke center-coupling, consisting of the ring A, having the opening B, formed with the shoulders D D at the bottom, and a smaller round portion at the top, in combina-- tion with the staple F, formed-with the narrow curved part G, and the shoulders E E, all substantially as and for the purposes described.
